Chasm

Welcome to Chasm, an action-adventure game in which you play a new
recruit undertaking your first mission for the Guildean Kingdom.
Thrilled to prove your worth as a knight, you track strange rumors that
a mine vital to the Kingdom has been shut down. But what you discover in
the mining town is worse than you imagined: The townspeople have
disappeared, kidnapped by supernatural creatures emerging from the
depths.
Honor-bound to solve the mystery and restore peace to the Kingdom, you
embark upon an epic adventure, with deadly battles against cunning
monsters, exploration of ancient catacombs and castles, and powerful new
equipment hidden at every turn. Though the overall story is the same for
all players, your hero's journey will be unique: each of the rooms has
been hand-designed, and behind the scenes Chasm stitches these rooms
together into a one-of-a-kind world map that will be your own.

CHASM is the perfect Metroidvania for those that desire a heavier emphasis on RPG systems at the expense of less flair on the action side of things. If you like the more RPG-centric Castlevania games from the PS1 and DS eras, there's a lot to love here. Lore nuts and audiophiles may not have a lot to get excited about, and it isn't as infinitely replayable as the procedural generation system would have you believe, but CHASM still proves to be a solid experience.
